Sensing that they were not alone on the deserted reef island, Emperor Nino began to pretend to be asleep, imitating loud snoring sounds through his nose, of course he squinted to see who was approaching them.It didn't take long, and a large shadow obscured the light of the solar lamp, it must be some giant, I'd better be awake and get up so the giant doesn't attack.The world of giants is not an ordinary world, they have their own language that no one else can understand now, naturally, until the Tower of Babel was destroyed, the whole world spoke the same language, so the giants themselves could talk to all other people easily.What is special is that giants live forever, which only gods can do, because before there were many giants among people, it happened that older giants had children at a very late age, which was impossible for ordinary people, that's the difference, now Nino plans to attract attention.That's why Nino started talking to himself, wouldn't the visitor recognize him in the shelter, there was a Chinese instrument standing in the corner that resembled a lute and a fiddle and an ancient Assyrian instrument, so he took it in his hands and started hitting the strings.The melody filled the room and the music could be heard through the transparent walls all the way to the sea, awakening the sea world.Suddenly, other giants appeared next to the shelter, moved by the melody of their youth, and stood with friendly and peaceful looks."Bravo," said the professor, waking up by himself."We finally found them, in fact the giants found us."Nino went outside to greet them, they embraced him and some of them recognized Emperor Nino.That evening they held a festival to welcome emperor Nino.On the deserted island at the crack of dawn, the laughter and song of the giants could be heard, and the giants celebrated that their emperor Nino came to visit them.Then they told him that the Yongle Emperor sponsored the construction of an underwater tunnel from the Dragon Hole to Beijing, so the Dragon Hole was named after the Emperor of the Ming Dynasty.Their job was to maintain the Great Wall after the construction of the tunnels and that was during the reign of the Ming Dynasty. Finally Nino found his fellow giants, he was surprised they were there on a secret mission of the Ming emperor, namely they had the task of building an underground road from the Dragon's Hole to Beijing, and that road ended under the spa of Princess Dan, so it remained a family secret of the emperors of the Ming dynasty.That road was built like the underground tunnels of Emperor Diocletian and Ninvia, the walls were covered with asphalt to prevent water from leaking, they were solid like real Roman walls and stone bridges that never age.The professor, as always, was delighted with this new historical discovery. "Today, underground atomic shelters are built by the richest businessmen, in the past presidents and emperors built emergency shelters.Our former president built a large concrete atomic shelter to live in in an emergency, which was never used, and has now become an art museum.This newly discovered tunnel could continue as the Roman road from the map that was from Europe to Asia.It would be a great atomic shelter for people if World War III breaks out.Of course, I want there to be no war anywhere and for the world to live well from Europe to Asia, to build tunnels of peace.The discovery of this tunnel will change a lot from now on.""Yes, now the giants can live freely outside the underground shelter.""If everyone knew that the giants still lived, their lives would be in danger, so it would still remain a hidden secret." Best is, I think that the giant mythology must remain just a legend for the public, so the giants will continue to maintain the Great Wall to be the protection and cultural treasure of China forever.
